I have a 98 Kia Sportage and it has no power going up hills. Any suggestions?

KIA Sportages have problems going up hills on highway speeds. The only thing I suggest would be doing some upgrades for your engine like a cone filter, switching your mechanical fan out for an electrical fan, and getting an aftermarket exhaust system.

I would say that you need to check your Cat Converters for clog issues! <img src="/forums/images/graemlins/kewl.gif" alt="" />

i have a 96 with a cone filter, and a 2.25 inch straight exhaust and i still struggle up hills. its just one of the down falls of having a 4x4 with halfway decent mileage.

Before you go adding on to your engine, adding un-needed parts. Try fixing the problem you have first. The Sportage is quit good at hills, just remember you can't do it in 5th, your going to have to gear down if you want to pass on a hill.

As for the lack of power, like mentioned elsewhere check the Cat, they are notourious for falling in on them selves, you could also check the spark plugs and coil packs, and timing belt. But the simplest check is the air filter and fuel filter.

Once you have solved your lack of power issue, then you can add on to your engine for even more.

If your kia is in good tune and you have a good cat the trick to hills in to shift down before you hit the hill or start loosing speed.
When my Kia was new we took a trip with some friends that had a 93 S10 blazer with a 4.3 V6 and an auto. He kept loosing me on hills untill I started shifting down at the bottom. I could out run him on any hill after that. I flew by him in 4th gear on one hill, he said he had in to the floor in 2nd gear when I went past him. Don't be afraid to your the full range or your tach, the engine can handle it.
